The national average price for on-highway diesel dropped for the fourth straight week according to figures from the Truckmiles.com website, collected daily by ProMiles software.

Normally, the U.S. Energy Information Administration publishes a weekly report detailing the average fuel price nationally, as well as the average price per gallon of highway diesel in 10 regions of the United States. However, the EIA posted a notice on its website Friday that stated the agency would be closed due to the lapse in appropriations caused by the federal government shutdown. The website notes the agency will cease to issue reports and data at this time.

The shutdown entered its 14th day on Monday.

ProMiles, which tracks prices daily, showed the national average at $3.887 on Monday, Oct. 14. The price was down one-tenth of a cent nationally compared to the average price reported to the website on Sunday, Oct. 13, and in keeping with a recent trend of slightly declining prices.

Truckers in Connecticut were paying an average of $4.375 per gallon, the highest in nation, while those fueling up in Missouri paid $3.662 on average.

In separate energy news, light sweet crude, the type of oil most associated with diesel production, was trading at $102.30 on Monday, up 28 cents a barrel as of midday.

In Europe, Brent crude was trading at $110.98 a barrel, down about 30 cents, according to Bloomberg.
